LimeSurvey

LimeSurvey is an open source survey application. LimeSurvey was formerly known as PHPSurveyor.

LimeSurvey enables surveys to be developed and responses to be collected and analyzed. LimeSurvey includes a wide range of built-in question types, and a range of flexible options. Surveys can include branching, different layouts and designs (using a templating system), and can provide basic statistical analysis of survey results. Surveys can be public, or can be strictly controlled through the use of unique tokens for each survey participant.

Features:

• 28+ question types: From simple single choice or multiple choice questions to complex Google Maps, file upload, equations and semantic differential question types - all at your fingertips.
• What you see is what you get: Edit your survey contents with our HTML WYSIWYG editor. Enter any HTML code if you need to. Use piping, placeholder, micro-tailoring to display answers from previous questions later on.
• Quota management: Create as many quotas as you like for your survey to ensure the required composition of your participant group. For example: You would like to question 500 women and 500 men of a certain age range.
• Skip logic / branching: Filter subquestions based on previous multiple choice questions or skip questions based on previous answers. That way you can avoid non-relevant questions and keep your survey participants happy.
• Analyze your surveys easier: Use LimeSurvey's inbuilt assessment score system to create valuable analysis scores in your answer options. Immediately assess during the survey to create scores visible to the participant or not.
• Invite and remind: Send survey emails using our email server or your own email server. Non-responding participants can be reminded by email. Automatic bounce handling marks email addresses as invalid, so they are not invited again.
• Anonymized responses - protected participants: If this feature is active you and your participants can be sure that there is no relation between the response and the participant. Once activated for a survey it is no longer possible to deactivate it once the survey was launched.
• Open and closed surveys: Enable public participation in your surveys or allow access just by personalized email invitation. You can also ask participants to register before participating.
• Offline functionality: Execute pen-and-paper surveys or personal surveys. After capturing the response data, enter it manually by using a convenient data entry mode and process it further.
• Visualize your response data: Create statistics and engaging graphs with a few clicks for all questions of your survey. Filter the results based on certain responses. Export the statistics to Excel or PDF.
• Export your responses: Export your responses as Microsoft Excel, Microsoft Word, SPSS, R, Stata, PDF or just as CSV file format.
• Dynamic questions: Use answers given to your previous questions to validate and refine your results. Our powerful expression manager serves this purpose.
